Specification of Letters Patent.

Appllcation'flled August 19, 1910. Serial No. 577,974.

To all whom it may concern:

Be it knownthat I, JOHN J. .KOHN, a citizen of the United States, residing .at Chisholm, in the county of St. Louis and State of ,Minnesota, have invented certain new and useful Improvements in Rail- Joints, of which the following is a specification.

This invention relates to rail 'joints and one of the principal objects of the same is to provide reliable and efiicient means for holding the rails at their meeting ends firmly in connection with the tics and to prevent 's reading, sinking, or displacement of the rai s at the joints.

Another object of the invention is to provide means of simple construction for holding the meeting ends of railway rails upon the ties and to rovide a spike of simple construction for ocking the base flange of the rail to the tie.

Still another object of my invention is to provide means for holding the rails at their meeting ends to the ties in a manner which will, permit the'rails to be joined and se cured in'place quickly and which will at the same time permit the rails to be with-' drawn for renewal or repairs.

These and other objects may be attained by means of the construction illustrated in the accompanying drawings, in which,

Figure 1 is a side elevation of a rail joint made in accordance with myinvention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a detail perspective view of one of the spikes for locking the rails in place.

Fig. 4 is a top plan view of one of the chair plates showing two of the spikes in section before the chair plate has been moved in the direction indicated by the arrow for looking the plate in position, said view showing the rail in dotted lines and broken away at the ends. Fig. 5 is a similar view showing the chair plate moved to the position for locking the shoulders of the spikes. under the chair plate. .Fig. 6 is a detail perspective view of a nut lock which I may use in connection with my invention.

Referring to the drawings the'nur'nerals 1 designate the meeting ends of the railway rails, said rails being of the usual or any suitable'type. The fish plates 2 are rovided with flanges 3 which overlie the ase flanges 4 of the rails, said fish plates being Patented Jan. 3, 1911.

heads of the spikes to engage the base flanges 1 of the rails.

The rail chairs each comprise a plate 6 provided at one corner with a lu 7, which serves to indicate the pro er position of the edge of the base flange 0 the rail. Formed in one side of the (plate is an L-shaped openmg or slot 8 an in alinement with said opening 1s a spike hole 9, which may be elongated either transversely or longitudinally of the plate 6. In the opposite side of the chair plate is formed an L-shaped an ular spike hole 10, as shown more clearly in i s.

4 and 5. On the under side'of each of t echair plates is a V-shaped r'bll, which is adapted to fit in a groove in he tie 12, said groove being longer than the rib 11 to permit the plate to slide transversely after the spikes have been driven and before the plate has been locked in osition. The spikes for use in the spike ho es 8 and 10 consist of a shank l3 havin an overhanging head 14 and a locking s oulder 15 disposed at one side of the shank 13 and at one side of the overhanging head 14.. Thelocking shoulders 15 are provided with tapering sides 16 runnin to a point 17, said locking shoulders being ormed integral with the sides of the shank of the spike, as shown more clearly ,in Fig. 3. The spike openings 8 and 10 are of the proper dimensions to permit the shank 13 and the locking shoulder 15 to be driven through the plate and into the tie. After the spikes have been driven through the openings 8 and 10 and into the tie with the heads 14 engaging the base 'fianges of the rails the plates 6 are moved in the direction indicated by the arrow in Fig. 4, thus moving the plates over the shoulders 15. An ordinary spike 18 is then driven into the hole 9 wi h. its overhanging head engagin the base flan e of the rail, andthus 10c ring the chair p ate 6 against lateral movement. The guide lugs 7 are utilized for indicating theposition of-the base flange of the rail. ,The rib 11 which engages a groove in the tie 12 serves to prevent the movement of the plates lengthwise of the rails and to'also serve as a guide for the chair plate relativelyto the tie.

The fish plates 2 are secured upon opposite sides of the web of the rails by means of bolts 19; The nuts 20 of these bolts are held ,in one ofthe fish plates to permit the nut locking plate to slide therein and to prevent 1ts turning after the nuthas been adjusted on the bolt and the end 23 of the locking plate bent down.

From the foregoing it will be obvious that a rail joint made in accordance with my invention can be quickly assembled, that the chair plate will holdthe rails firmly in position to prevent movement in any direction, that the rails can be quickly laid, and that repairs can be readily m'ade owing to the fact that but a single spike 18 may be withdrawn before the plate is moved to one side to permit the withdrawal of the plate and rail from the tie. I

My invention is of simple construction, can be manufactured at low costand provides strong, durable and eflicient'means for holding the rails in proper position and to prevent undue movement in any direction.

I claim 1. A rail joint comprising fish plates, chair plates underneath the base flanges of the rails, said chair alates being provided with ribs on their nn ersides to fit grooves in the ties, and L-shaped boltholes through vthe plate, .in combination With spikes having shoulders at the sides thereof and formed integral therewith, said shoulders being tapered to a point at their lower ends to be and a locking spike for holding the plateagainst lateral movement.

In testimony whereof I aiiix my signature 1n presence of two witnesses.
